Good day,
three weeks ago I received a lower bridge: both central incisors were extracted, and there is a crown on both lateral incisors and canines - all porcelain. My problem is that I have a metallic taste in my mouth (the adjacent bridge was ground down and a little metal is visible). Can anything be done about this?
I still have not got used to all six new crowns after three weeks, and I have speech problems (sibilant and postalveolar sounds). It seems to me that my tongue has too little space.
Is there any solution?
Thank you in advance for the answers and kind regards, Nada

Dear Sir/Madam!

A metallic taste is most often the result of polymetallism, or the presence of different metals in the mouth. Metals with different redox potentials (degrees of solubility in an electrolyte) form a galvanic cell in saliva (which is in fact an electrolyte and conducts electric current), similar to a battery. You perceive the presence of galvanic current as a metallic taste. Most often we have to remove one of the metals (an amalgam filling), or, if there are no such fillings, one of the bridges that are evidently made of different metals.
As for pronunciation and similar disturbances, for now I can only advise patience and time. I could not give any further comments without a clinical examination.

Have a nice day.
